Sensitivity and lower limit detection determined of XRF for copper and zinc suspended in lubricated grease

الملخص EN

In this work different weight percent of copper and zinc powders of 20 μm particle size were blended carefully with grease, and the final weight of samples are 2 g.

The samples were placed in containers were made from tephlon of 2.5 cm as a diameter.

The bottom window of container was fitted with 6 μm mylar film.

The samples were subjected to X-ray fluorescence to measure the Cu Kα and Zn Kα lines intensities .

Sensitivity (m) and Lower Limit Detection (LLD) were calculated and plotted against the weight fraction for all samples.
